The present invention relates to slicing.

machines, andparticularl'yto thattype of machine embodying; a reciprocating carr age in which the bearing-members on jthe carriage slide upon fixed guides on the :base of the machine. It isvery important in devices of this nature. that theguides be lubricated and the present inventionhas for one of its'objects the provision of eflicient means for. accomplishingthis result. I

Another object of this invention is to pro vide a simple automatic means for lubricating the rods during the reciprocating motion of the carriage.

Still another object of the invention is to provide lubricating rings surrounding the guides, which rings are adapted to be rotated by the reciprocation of the carriage and convey the lubricant from troughs to the surfaces of the guides. I

1 Still another object of this invention is to provide a reservoir for the lubricant, which is a part of the carriageitselfsand reciprocates'therewith.

Other objects of the invention will appear hereinafter, the novel features and combina-, tions being set forth in the appendedclaims'.

In-the drawing Fig.1 is a front elevation otthefmachine, with a portion of the carriage broken away to. show a cross-section of some of the parts and to expose other .parts to view; 7 Fig.2 is an isometricview ofthe means for automatically rotating the lubricating ring on the guiderod;

fied form of a lubricating ring for supplying oil to the guiderod; and a I Fig. 5 is'a detail view of the ring shown in Fig.4.' Y ,T i The slicing.imachineicomprises a base 1 and a carriage 2 whichhas formedintegral therewiththe bearings 3'slidable upon-the guide rods 4 supported by the brackets .5.

on the base, member 1. .A cross-slide 6. has

uprights 7 carrying a clamping member Q8 adapted to clamp the material9 to the crossslide. The cross-slide is adapted to-be ad-e vanced with ,a step-by-step motion toward the knife/10f after each reciprocation :of the The knife 10. is;

carriage past I the knife. supported in a bearing 11 mounted on the basel. The carriage isreciprocatedupon formlng a connection between the shaft 15 and the crank.

On the under substantially semi-circular troughs 16 adapted tofform a means to holdilubricant fora purpose presently to bedescribed'. The downwardly extending flanges 16 at opposite ends of the carriage form the end portions of the troughs 16. Surrounding the-guide rods 4: are-the rings 17 adapted to extend down into the'troughs 16 so that when they are rotated thelubricant is carried to the surfaces of the guide rods. To rotate each of the rings17, projections 18 are provided on the bearings 3 and. project inwardly. toward the ring, as

7 side ofthecarriage'Zadjae cent opposite outer edges thereof are two best illustrated in. Fig. 2., Asthe carriage reeiprocates, first one of the projections 18 engages'a ring 17 and thenthelother projection 18 engages a ring, andas each'projection comes into engagement with the ring, the ring is raised slightly on one side and as the pin is withdrawn the ring tends to rotate slightly as it resumes itsnormal positionon the guide rod. The engagement of the pro- ,jection 18 with the ring 17 also causes it to rotate slightly due to the fact that it is pulled to one side'and itis also caused to slide along the rod due to the push given it by the proj ection' 18. This movement of the ring distributes the lubricant over the surface of the guide rod in a Very efficient manner and the construction is simple and rugged and will not easily get out of order. From the above description, the operation of the device is apparent.

In Fig. 3 is shown a modification in which the base 1, the carriage 2, guide rods 4, supports 5 and cross-slide 6 carrying the uprights 7 are the same as the corresponding parts shown in Fig. .1, but in this modification the troughs 20 are not supported upon the carriage, but are supported on the guide rods and extend substantially the length thereof to form in addition to a lubricant trough, a covering means to protect the guide rods from foreign matter which has a tendency to accumulate thereon. The troughs 20 are in the form of tubular members which are supported by members 21 on the guide rods 4 at the opposite ends thereof. Each tubular member has a slot 23 through which a portion of the bearing member 19 extends so as to form a connection between the bearing and the carriage. This slot is located on one side of the tubular member so as not to provide an opening which will come directly over the guide rod 4, but it will be understood that the slot may be located in other positions than the one shown to' accomplish the same result, or if the tubular member is used just as a cover, the slot may be located at the lower portion of the tubular member, and if used only as a lubricant trough, the slot may be placed on the upper side of the tubular member. In this instance, the carriage is reciprocated by the crank 12 and pitman 13, the latter being pivotally connected to an extension 13' of the bearing 19. The bearings 19 carry pins 18 to engage the rings 17' mounted in the same manner as shown in Fig. 1.

' Fig. 4: is a section taken between the eX- tension 13 on the bearing 19 and the tubular member 20 shown on the left in Fig. 3 and is a view looking toward the left in that figure, but a different form of lubricating ring is shown in this figure. The lubricating ring comprises the circular member 24 which may be rectangular in cross-section, but is not necessarily so. On the outer surface of said ring are the projections or vanes 25 and these vanes are set at an angle, asillustrated. In this figure, the projections 18 and 18' shown in Figs. 1 and 3 are omitted since the vanes 25 cause the ring to rotate and carry the oil or other lubricant in the trough 20 to the surface of the guide rod. As the carriage reciprocates, the bearings 19 at opposite ends of the carriage alternately strike the ring 24 and carry it along the rod and the reaction of the vanes 25 against the lubricant in the trough 20 causes the ring to rotate slightly and carry the oil to the surface of the guide rod, as will be readily understood.

It will be noted that the flat faces of the bearings 19 which engage the corresponding fiat faces of the ring 24 provide a means whereby the ring is maintained with its axis in substantially a horizontal position parallel to the guide rod 4: as the ring rotates about the guide rod.

While applicant has illustrated the ring in Figs. 4 and 5 as applied to a machine in which the trough is stationary, it is obvious that the ring shown in Figs. at and 5 can be used in place of the rings shown in Figs. 1, 2, and 3, and when so used, the projections strike the rings, tilting the rings, and the vanes 25 bring a considerable quantity of lubricant onto the guide rod which is to be lubricated.

Obviously those skilled in the art may make various changes in the details and arrangement of parts without departing from the spirit and scope of the invention as defined by the claims hereto appended and I wish therefore not to be restricted to the precise construction herein disclosed.
